Using the improved brick-wall film model we calculated the entropy of Dirac field in a generalized non-stationary spherically symmetric black hole with charge. From the point of view of the model these entropies are nothing but the entropy of the black hole. The result showed that this entropy is proportion to the area of event horizon.
